Answer:
A solution is always transparent, light passes through with no scattering from solute particles which are molecule in size. ... If a suspension is allowed to stand the particles will separate out. A colloid is intermediate between a solution and a suspension. While a suspension will separate out a colloid will not
Answer:
Solutions Colloids Suspensions
Homogeneous Heterogeneous Heterogeneous
Particle size: 0.01-1 nm; atoms, ions, or molecules Particle size: 1-1000 nm, dispersed; large molecules or aggregates Particle size: over 1000 nm, suspended; large particles or aggregates
Do not separate on standing Do not separate on standing Particles settle out
Cannot be separated by filtration Cannot be separated by filtration Can be separated by filtration
Do not scatter light Scatter light (Tyndall effect) May either scatter light or be opaque
